As you might have already noticed, i switched my commenting system to Livefyre. If i got it right it's relative new but it seems to better for my needs than well established Disqus commenting system. Disqus gained popularity in last two or three years and I tried Disqus some time ago too, but didn't liked it's Wodpress Plugin. Especially i didn't liked the poor java Script implementation, which was not crawable by google (maybe it's got better now). Livefyre promise to be SEO friendlier out of the box. Indeed Livefyre WP-Plugin renders all the comments to html, and I saw them by switching all the java-scripts off ;)
Additionaly i read many comparisons on that topic, like this one: Disqus vs Livefyte.
